ABSTRACT:
An injection molding nozzle assembly is disclosed comprising a one-piece central body having a generally-cylindrical first section defining a radial surface and terminating in a face and a generally-cylindrical second section defining a radial surface extending in axial alignment with the first section in a direction opposite to the face. A central passage extends axially within the second section, and one or more flow passages extend between the central passage and the face of the first section. At least one of the flow passages has an aperture in the radial surface of the second section which receives a plug. A nozzle seal is removably secured to each of the flow passages on the face of the first cylindrical section. A flange is provided that has a generally-cylindrical central opening that is to be received by the second cylindrical portion of the body and is affixed to the body so as to overlie each plug.
